Here's a taste... pardon the pun.
The Eucharist, the source and summit of the Faith, is the greatest gift we can receive as Catholics. But some of the Faithful cannot receive that same gift, despite their desire to be one body with their fellow Catholics in Christ.
They are celiacs: individuals who cannot ingest wheat or gluten — including rye and barley – without a negative autoimmune reaction and serious intestinal damage.
According to a study by the University of Maryland School of Medicine in Baltimore, almost one out of every 133 Americans suffers from celiac disease. That means that there may be one celiac, or more, in every Catholic parish with more than 100 members in the United States.
That celiac may even be the priest of the parish or the bishop of the diocese, like the co-adjutor Archbishop of Cincinnati, Dennis Schnurr.
Viable options exist for those who suffer from celiac disease to participate in the Eucharist, but much confusion and some ignorance still remains. What alternatives are there from receiving a traditional wheat host? And how can the Church, and her priests, serve parishioners with celiac better?
